Titanium dioxide thin films Preparation and Characterization

8.7. .) From the dynamic contact angle measurement data can also be seen. Dynamic contact angle of the advancing contact angle is small, the water is zero, indicating a strong hydrophilic, and in the non-polar diiodomethane solution,[link widoczny dla zalogowanych], the surface contact angle smaller. Show a strong lipophilic, ultra-hydrophilic titanium oxide surface structure is the cause of changes in UV irradiation, the titanium dioxide valence band electrons are excited into the conduction band, electronic and air transfer to the titania surface, the surface the formation of electron hole pair, e and T reaction, the hole is with the film surface reaction of oxygen ions were generated Ti, which is obtained by photoelectron spectroscopy results - titanium films by two different valence material results are consistent. At this point, the air in the dissociative adsorption of water molecules in the oxygen vacancy in a chemical adsorbed water, chemical adsorbed water can be further adsorbed moisture in the air, that is, Ti \region remains hydrophobic, which in the uniform distribution of titanium dioxide formed on the surface of the hydrophilic and lipophilic micro-area, the performance of titanium dioxide in the macro nature of both the hydrophilic and edible vegetable oil. surface for 78.13eV,[link widoczny dla zalogowanych], show that the titanium oxide film strong activity. 4 Conclusion (1) calculated using the Warren-Averbach crystallite size distribution, micro-strain and the XRD patterns of TiO: static lattice distortion of diffraction intensity are described in TiO: micro-structure for research and development TiOz provides a characterization of functional properties and evaluation methods, such as crystallite size distribution, micro strain and lattice distortion were characterized by static methods. (2) electron microscopy analysis showed that the particulate titanium oxide film distribution,[link widoczny dla zalogowanych], no larvae L-dong,[link widoczny dla zalogowanych], SEM observed particles gathered by the small grain size into the second, fracture surface morphology is smooth, that the film showed obvious fracture characteristics of ceramic materials. (3) dynamic contact angle measurement results showed that the titanium oxide film has both strong hydrophilic and a lipophilic nature, while the thin film materials with strong surface activity.
